Mrembo

Jonathan Portman, who operates out of Upper Lambourn in Berkshire and has sent out 46 winners already this season, knows this horse well. He trained her mother too, which gives him a particular feel for what she needs. His take is straightforward: she has to be in the right mood, she loves fast, dry ground, and the tactics need to suit. At Salisbury recently she was asked to go too hard too early and could not sustain it — the kind of small, fixable mistake that matters a lot with a horse who runs on feel rather than raw ability. The plan, he says, is a trip to Brighton later in the month, and he is quietly confident she has at least one more win in her at her current level.

That level is Class 5 — the bread and butter of British racing, several rungs below the glamour events — and it is worth being honest that she has won only 1 of her 23 races in that grade, a rate of around 4%. However, there is a specific place where everything clicks: Bath. She has won 3 of her 7 races there, making her almost a one-in-two shot at a track where most horses win far less often. Her very first win came at Bath in May 2022, and the place clearly suits her. Her most recent victory came at Windsor just five weeks ago on 25 May 2026, so the winning thread has not gone cold.

Her most regular partner in the saddle is Olivia Tubb, who has ridden her in 21 of her 50 races and picked up 3 of those 6 wins together — a win rate of about 14%, comfortably better than her overall career average. That kind of established partnership matters with a horse as temperament-dependent as this one. When the ground is right, the tactics are right, and Tubb is aboard, Mrembo is a horse worth keeping an eye on.
